* nand/spl: Assuming a static nand page size to reduce code sizeMatthew McClintock2011-04-15-5/+5
| | | | | | | | | Change variables to const to reduce code size, these values are hardcoded via defines anyways so we might as well assume they are constants Signed-off-by: Matthew McClintock <msm@freescale.com> cc: Scott Wood <scottwood@freescale.com>
* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-2/+2
| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

* ppc/85xx: Fix inclusion of 83xx immap in 85xx buildsKumar Gala2009-11-04-1/+0
| | | | | | | | The nand_boot_fsl_elbc.c is shared between 83xx & 85xx however we should not be including the immap_83xx.h when building 85xx. We can just get this all from common.h Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* NAND boot: fix nand_load overlap issueMingkai Hu2009-08-21-1/+1
| | | | | | | | | The code copy data from NAND flash block by block, so when the data length isn't a whole-number multiple of the block size, it will overlap the rest space. Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND: Fix cache and memory inconsistency issueDave Liu2009-01-23-0/+5
| | | | | | | | | | | | | | | | | | We load the secondary stage u-boot image from NAND to system memory by nand_load, but we did not flush d-cache to memory, nor invalidate i-cache before we jump to RAM. When the system has cache enabled and the TLB/page attribute of system memory is cacheable, it will cause issues. - 83xx family is using the d-cache lock, so all of d-cache access is cache-inhibited. so you can't see the issue. - 85xx family is using d-cache, i-cache enable, partial cache lock. you will see the issue. This patch fixes the cache issue. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Make Freescale local bus registers available for both 83xx and 85xx.Haiying Wang2008-10-29-2/+2
| | | | | | | | | | | | | - Rename lbus83xx_t to fsl_lbus_t and move it to asm/fsl_lbc.h so that it can be shared by both 83xx and 85xx - Remove lbus83xx_t and replace it with fsl_lbus_t in all 83xx boards files which use lbus83xx_t. - Move FMR, FIR, FCR, FPAR, LTESR from mpc83xx.h to asm/fsl_lbc.h so that 85xx can share them.

* NAND boot: MPC8313ERDB supportScott Wood2008-08-12-0/+150
Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
